nonlinear dependency
 

Greetings!

I would like to know if it is possible to add to OpenFOAM a nonlinear dependency of something. For example (in my case), permeability for ferromagnets. How I see it: there is a file with B and H relation at some points and curve is generated from them. OpenFOAM picks the correct value from this file. Is something like this possible?

Sincerely,
Martin
